How to Genei-Jin and Hadouken (without beating
Ryu).

First, you must enter a code at the "Press Start" screen. This will give the Mega Buster a weapon meter.

Code: At the "Press Start" screen, hold Shoot and Jump for about 6 seconds. There will be a chime to let you know that this worked.

Hadouken: Once you have entered the code, press (down, forward+Shoot). You can charge the Hadouken for a Red Hadouken.

Genei-Jin: Once you have entered the code, press Shoot+Swap1. This activates Genei-Jin, which uses the Mega Buster's weapon meter. I am not sure you can deactivate the Genei-Jin; just run out of meter or die.

So, this is what I know. I really wonder if there are other hidden moves in this mode.---Live: SpootzPSN: SPTwhte

I thought this was going to be a troll. But no, it worked! XDActually, I'm pretty sure that this is not Genei-Jin, but Sei'ei Enbu, Yang's super. In fact, Rose does this same thing in the Alpha games.Geez, this game has so many neat little cheats. How did you find this out?---http://myanimelist.net/profile/FFandMMfanI'm gonna tear it apart and rebuild it twice as good! I-I'm gonna RENOVATE your ass! - Kanji Tatsumi

It is indeed Sei'ei Enbu, but I figured most people wouldn't recognize the name of that move. People recognize Genei-Jin though (and it looks like it even if it doesn't work the same way).

I figured it out through dumb luck. I was starting up the game when my wife called, so I alt-tabbed the game (apparently while I was hitting Shoot+Jump) at the press start screen. I heard the chime even though the game wasn't maxed. So, this told me that it had to do with the Press Start screen. I figured it had to do with either waiting or holding a button, which led me to try holding every combination of button I could think of. Then I just had to figure out how to do Genei-Jin (hadouken was obvious). So, I pressed buttons randomly. YAY!---Live: SpootzPSN: SPTwhte
